The Dutch groundwater quality monitoring network includes 390 monitoring points. The frequency of sampling is once a year. The objectives of the network are: - to make an inventory of the present quality in relation to soil use, type of soil and hydrogeological conditions ; - to distinguish long term changes in quality ; - to provide data for quality control and groundwater control ; - to indicate the extent of human influence on groundwater quality. This report gives the results of analysis in 1992 from 25 monitoring points in the province of Noord-Holland.
